Pressure equipment autoclave bonding

The investigations of the reaction of ketoximes with acetylene have shown that the superbase system KOH/DMSO essentially facilitates vinylation of pyrroles with acetylene. This finding constitutes the basis of a new efficient method for vinylation of componnds having the N-H-bond. The process fnndamentally differs from the known protocols since it is brought about under atmospheric pressnre at moderate temperatnres (80°C-100°C). The method is recommended for vinylation of any NH heterocycles (resistant to the action of alkalis) in simple reactors. Apart from the obvions promise for industry, the method is also indispensable for laboratories that do not have special operating building and equipment (autoclaves working with acetylene nnder pressure). 

Large bonded areas, such as on aircraft parts, are usually cured in an autoclave. The parts are mated first and covered with a rubber or film blanket to provide uniform pressure distribution. The assembly is then placed in an autoclave, which can be pressurized and heated. This method requires heavy capital equipment investment. 

The temperature and pressure employed in the fabrication of the bonds were beyond the capability of conventional processing equipment. Conventional autoclaves are defined as those with maximum operating...
